Abstract
A humidity control system () includes a refrigerant circuit () including a compressor (), a first adsorption heat exchanger () carrying an adsorbent thereon, an expansion valve () adjustable in opening and a second adsorption heat exchanger () carrying an adsorbent thereon, supplies humidity-controlled air to a room by operating alternately in a first batch mode in which the second adsorption heat exchanger () adsorbs moisture in air and the first adsorption heat exchanger () releases moisture to air and a second batch mode in which the first adsorption heat exchanger () adsorbs moisture in air and the second adsorption heat exchanger () releases moisture to air, and controls the opening of the expansion valve (), when a valve control start time has come a predetermined time after the start of each batch mode, so that the degree of superheat of refrigerant in the refrigerant circuit () reaches a predetermined value.
